Is Laser Hair Therapy Safe for your Eyes?

Laser eye therapy and laser hair therapy differ by one word, and both are intended to correct either vision or hair loss. We wouldn’t recommend using a surgical laser on your scalp. What about the other way around? Can staring into a Theradome Laser Helmet damage your eyesight?

Time to recall your high school physics classes. Light is composed of photons emitted at various wavelengths. A shorter wavelength implies that a light beam has more energy, while a longer wavelength therefore implies it has less energy. Think of a “wavelength” as the distance between two crests or troughs of an oscillation. If a light wave is advancing slowly, it has less energy and its wavelength is thus longer. But if a photon is bouncing up and down quickly, as you may have guessed, not only is its wavelength shorter, but its energy is through the roof.

Yes? Good.

A vast majority of the electromagnetic spectrum is not visible to the human eye– we can’t actually “see” radio waves, nor can we can detect, without the right equipment, the presence of high-energy x-rays and their harmful radiation. These have wavelengths of less than 10 nanometers (nm), and have enough energy to penetrate through the muscles and flesh of your body, hence imaging the bones of your skeleton.

So what does this have to do with laser hair treatments, more specifically laser treatment for hair loss conducted with the Theradome Laser Helmet? A lot. You may recall that laser light is of the color red, which falls between a range of 622 nm and 780 nm. Nope– not very energetic when compared to x-rays, or even harmful UV light, which propagates at right below 400 nm.

So should you wear protective goggles of some kind when undergoing one of your cozy, Theradome laser hair treatments at home? No need to. And it isn’t just because its lasers are not equipped with collimated lenses– meaning their light propagates, which diffuses their power.

Logic dictates that you won’t stare at the sun, and if you do, you’ll end up feeling the urge to blink. And unless you’re a robot, you won’t be able to fight off your body’s survival instincts to preserve your eyesight. The same happens with red light. In the case of our Theradome laser hair restoration helmet, not only are our eighty 678-nm lasers not collimated, as mentioned above, but chances are you wouldn’t be able to stare directly into the lasers before blinking and thus avoiding damage to your eyes.

So unless you’re strapped to a chair with your eyelids forced open by a diabolic machine, being tortured by a troll armed with a laser helmet in a dungeon somewhere, your eyesight should be just fine.
